498 Meteorological Observations. 



able contrast to the body of the animal, which at its upper part is of 

 a dark orange colour, gradually assuming a paler tint towards the 

 base ; numerous white sucking-pores are disposed over the upper 

 surface, and afford points of attachment to surrounding substances, 

 when required to conceal the body ; they also give exit to the con- 

 voluted filaments, which are abundantly thrown out from them and 

 the mouth, when the animal is irritated. Its natural haunts appear 

 to be narrow crevices of rocks, into which it can retire when alarmed, 

 and I was prevented obtaining many specimens by their having 

 chosen such inaccessible hollows for their residence. Four or five 

 examples were, however, procured at extreme low-water mark, from 

 the very productive rocks outside Dartmouth harbour, and, excepting 

 in size, presented no points of difference. I propose for this species 

 the name ofvinosa. — Proc. Zool. Soc, June 10, 1856.
